Diodes Incorporated B360AE-13

Overview

B360AE-13 from Diodes Incorporated is a 60 V, 3 A surface-mount Schottky barrier rectifier in SMA package, featuring 0.65 V max forward voltage at 3 A and 0.2 mA max reverse leakage at 60 V/25°C, optimized for boost, blocking, and recirculating diode roles in DC-DC converters and power supplies.

For engineers reviewing the B360AE-13 datasheet, B360AE-13 pinout, B360AE-13 application, or B360AE-13 equivalent, key selection criteria include its low VF for efficiency-critical 3 A rectification, high-temperature IR stability up to +150°C, RoHS-compliant matte tin terminals, and IATF 16949-manufactured construction suitable for automotive-grade designs.

Technical Context

This Schottky rectifier uses a planar epitaxial silicon structure with metal-semiconductor junction to achieve low conduction loss and fast switching without minority-carrier storage delay. Its 60 V VRRM rating supports standard 48 V and 36 V bus applications with margin.

Thermal design is enabled by RθJA = 60°C/W (FR-4, 1"×1", 2 oz) and RθJC = 30°C/W, allowing sustained 3 A operation up to +125°C ambient when properly heatsinked via the cathode-band-marked SMA case.

FAQ

What is the maximum junction temperature and how does it affect derating?

The B360AE-13 has a maximum junction temperature of +150°C. Its DC forward current must be linearly derated from 3 A at +75°C ambient to zero at +150°C, per Figure 4 in DS39350 Rev. 3–2. This requires thermal design using RθJA = 60°C/W on standard FR-4 to ensure TJ stays within limits under full load.

Is B360AE-13 qualified for automotive applications?

B360AE-13 is manufactured in IATF 16949-certified facilities and supports automotive change control, but it is not explicitly AEC-Q101 qualified per Diodes' public documentation. For AEC-Q101-compliant alternatives, contact Diodes' automotive team directly for PPAP-capable variants.

How does the reverse leakage compare at elevated temperatures?

At +125°C and VR = 60 V, IR is ≤25 mA (typical curve shows ~10 mA), significantly higher than the 0.2 mA max at 25°C. This behavior is inherent to Schottky physics and must be accounted for in high-temperature hold-up or blocking designs where leakage impacts standby power or voltage regulation.

Can B360AE-13 replace B350AE-13 in existing designs?

Yes - B360AE-13 is a direct functional upgrade to B350AE-13, sharing identical SMA package, pinout, and thermal characteristics, while offering higher 60 V VRRM (vs. 50 V) with no increase in VF or IR. No layout or thermal redesign is needed for drop-in replacement where 60 V margin is beneficial.
